My advice would be to compare several brokers and find the one that is suitable and that can be profitable during live trading.
Good suggestions, can also add fxview and pepperstone, both are solid when it comes having a good ecn broker.The best way to find a good broker is to read reviews from other traders or discuss brokers on forex forum sites.
In my opinion, regulated ECN brokers are good; brokers such as Etoro and FP Markets are also suitable due to their reliable trading conditions.
